How to reveal hidden characters from scanned PDF417

I currently use chr(4), chr(29), and chr(30) for <GS>, <RS>, <EOT> separators and not in that order. Other organizations may use Hex or tilde as separators. I get the PDF417 through the use of IDAutomation's Java Barcode Packages from an earlier version we purchased. I use IDAbarcode_pkg.pdf417 to encode and return the blob of the PDF417 in BI Publisher. Is there a way to pass scanned text and have the text decoded to display the hidden character with <GS> like the ASCII Decoder with a similar call to idabarcode_pkg or JavaScript? Since different organizations use different separators, I can't do anything without revealing the codes. I don't know how to use Visual Basic from PLSQL. Would a more updated JavaScript have the decoder function? If you can be specific as what we need please.

Operating System:
Solaris and Windows 10

Application:
Oracle Forms with PLSQL. I use BI Publisher to display PDF417

We are not aware of a method that can reveal the hidden characters in JavaScript. I recommend using the code example from the ASCII String Decoder and try to find similar functions in the environment you are working with.
